Acutally, I was responding to the comment: "where she was the night she disappeared". That was the point of my comment.
If the phone trail is tracked, as I am sure it was,
You believe all phones are tracked and the data kept for review later?
And the location of the phone was most certainly close to where the missing student was at the same time.
Probably, if such data existed. Life isn't a TV show. As for real life technology abilities, do you believe the police are not aware of them?
“You believe all phones are tracked and the data kept for review later?”
Yes, I do. Just as all emails and phone calls can be retrieved.
Recently, a woman was murdered by a marine she was having an affair with. He met her secretly in the mountains, killed her and threw her down into an abandoned mine shaft, one of hundreds in that area. Her body was retrieved fairly quickly. Cell phone tracking got them close enough to find her.
“You believe all phones are tracked and the data kept for review later?”
If the phone has a charge, you can track its general vicinity every few minutes from pings to the cell towers. Those records are definitely retained.
